Definitions
- the invention relates to a circuit arrangement for supplying a direct current consumer with constant current from input direct voltage sources of different voltages using a self-oscillating flyback converter.
- a voltage transformation which can be carried out capacitively or inductively, is required to adapt the small devices or accumulators to the different voltages.
- a transistor converter circuit is known from DE-A-20 14 377, with the aid of which a charging current for an accumulator and, on the other hand, a higher direct current for driving a motor can be generated from an AC mains voltage.
- a high-frequency flow converter with a saturable core is provided, which is connected on the primary side to the rectified mains voltage and supplies the desired currents on the secondary side.
- the known circuit can only be operated at a certain mains voltage, so it does not automatically adapt to different voltages. Since the core of the converter saturates, the efficiency is low and thermal problems arise.
- the secondary winding of the transformer is connected in series to an RC element and the switching path of a second transistor, the base of the first transistor being connected to the connection of the switching path of the second transistor to the RC element.
- the flyback converter is controlled in such a way that the current delivered to the consumer is constant over a wide input voltage range.
- the current flowing in the blocking phase of the flyback converter into the consumer, ie into the accumulator, depends on the energy content of the transformer Beginning of each blocking or pass phase. This circuit ensures that the same energy content is always present in the transformer at the time of switching off.
- the object of the invention is to provide a circuit arrangement for supplying a direct current consumer from input direct voltage sources of different voltage using a self-oscillating flyback converter with a transformer which supplies a direct current consumer of lower voltage with a constant current even in the event of fluctuations in the direct voltage input.
- the solution according to the invention ensures that a constant charging current for charging an accumulator is present at strongly fluctuating input voltages or different voltage values at the input of the circuit arrangement.
- This constant charging current is of particular importance in the case of sensitive nickel-cadmium cells, which can be destroyed at an early stage if the charging currents differ widely.
- the emitter resistor is connected to a tap of the secondary winding of the transformer.
- This embodiment proves to be particularly idle-proof, has only a slight heating of the individual components during operation and, without additional expenditure with regard to the components to be used, has a sufficient circuit reserve for the extreme load in the case of deeply discharged batteries.
- the series connection of a first resistor, a second resistor and a battery to be charged by the circuit arrangement is provided between the emitter of the transistor and the reference potential, the connection of the secondary winding of the transformer facing the reference potential being at the connection point of the two resistors.
